Helpers that iterate over extent buffer pages set up several variables, one of them is finding out offset of the extent buffer start within a page. Right now we have extent buffers aligned to page sizes so this is effectively storing zero. This makes the code harder the follow and can be simplified. The same change is done in all the helpers: * remove: size_t start_offset = offset_in_page(eb->start); * simplify code using start_offset Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Signed-off-by: David Sterba <dsterba@suse.com> |

README
Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
